MILLWALL have not been given an increased allocation for their FA Youth Cup quarter-final against Chelsea at Stamford Bridge next Thursday.
The Lions have "filed a written complaint with the relevant authorities" after they believe they were given "an unnecessarily small allocation" of 1,007.
Those tickets sold out, but talks with Chelsea failed to yield an increase.
In a statement, the club said: "Millwall Football Club regrets to inform supporters that no further tickets will be made available for the FA Youth Cup Quarter-Final tie away to Chelsea on Thursday, February 27.
"The club is immensely disappointed by what it believes to be an unnecessarily small allocation and has filed a written complaint with the relevant authorities. Millwall have fought against the decision to provide such a minimal ticket allocation from the off and the club is also of the belief that limiting the overall attendance undermines the integrity of the competition.
"As well as denying more fans the opportunity to watch the game, it also hugely restricts the number of players' family members and friends who can attend on what is the biggest occasion of their careers to date.
"The match is all-ticket and the club urges fans who have not been able to purchase one not to travel to Stamford Bridge on the night. It is hoped that a live stream will be available for all Lions supporters to view free-of-charge."
